The leaked specifications of the device have now been confirmed. The Lumia 1520 uses a top of the line Qualcomm Snapdragon 800 processor, 2GB of RAM and a 20-megapixel PureView camera with brand new 'Nokia Camera' app and functionality.

A series of new apps will launch alongside the 1520. The Nokia Camera app allows users to switch camera modes and focus.

Nokia Here Maps has been integrated with Nokia's photo tech to create an app called 'Storyteller'. The aim of the app is to create location-based photo sets to help you explore and browse everything you capture with the 1520's camera.
